After more than a year and a half together, and a six month engagement, Chanel Iman and her rapper beau ASAP Rocky have reportedly called it quits.

E! News reports the pair - who first started dating in early 2013 - split up a few weeks ago.

The 23-year-old model and the 26-year-old rapper kept their relationship largely under wraps, so it comes as no surprise their split was equally quiet.
